This paper presents the evaluation for the safety performance of the concrete tower, the performances of the concrete tower cracking behavior is simulated and studied experimentally, which make safety evaluation with fractal theory and verify the method through the 1:4 scale model in laboratory based on fractal theory. The results show that the damage evolution of concrete tower has fractal characteristics, which can quantify the relationship of carrying capacity of cable-stayed tower and the fractal dimension to evaluate the safety performance of the cable-stayed tower.
